This invention relates to a heat exchanger type burner base unit (100), comprising: a burner base (1) having: a burner air inlet for supplying burner air, an exhaust gas inlet for drawing exhaust gas, and a combustion gas inlet; a heat exchanger (20) connected to the burner base (1) having a heat exchanger body (21), the heat exchanger body (21) having at least two separate flow channels for guiding counter-flowing fluids, and the heat exchanger body (21) further having an inner cavity (27) for forming or guiding through at least one combustion gas conduit (31, 32); characterized in that the burner base (1) is designed as a flat burner base element (10) or includes a flat burner base element (10). 0); the burner base element (10) includes at least one gas passage opening (14) and / or at least one gas passage opening (13) and / or at least one opening, the at least one gas passage opening (14) being used to connect the burner air interface (33) to a flow passage in the heat exchanger (20), the at least one gas passage opening (13) being used to connect the exhaust gas interface (34) to one of the flow passages, and the at least one opening being used to connect to the combustion gas interface (31, 32); a flat support surface (10.3) is provided on the front side (10.1) of the burner base element (10) facing the heat exchanger (20) for connection; and the heat exchanger is integrally connected to the support surface (10.3).

A porous combustor liner for a gas abatement system is provided. The combustor liner includes a hollow body defined by a wall, the wall including a plurality of interconnected substantially concentric layers. Each layer of the wall includes a substantially regular pattern of voids; wherein the substantially regular pattern of voids of each layer is configured such that it is out of phase with one or more adjacent layers, and wherein the wall includes a sufficient number of layers arranged such that the wall is optically opaque when viewed from the outside along any radially inward direction normal to the wall.

A burner includes a mixing chamber having therein a space in which fuel and air are mixed to form a mixture, a chamber lower cover that is coupled to the mixing chamber while covering an opening formed in the mixing chamber in a reference direction and has a combustion opening opened in the reference direction, a porous distribution unit that includes a metallic sintered material, through which the mixture passes in the reference direction, and covers the combustion opening, a distribution plate that has a plurality of distribution through-holes, through which the mixture passing through the porous distribution unit passes, and covers the combustion opening on the downstream side of the porous distribution unit in the reference direction, and an ignition unit that covers the combustion opening on the downstream side of the distribution plate to ignite the mixture passing through the distribution plate.

A hydrogen gas burner includes a first, axially extending, tubular pipe having an axial slot in a sidewall thereof. An axially elongate duct projects radially outwardly from the axial slot and is in fluid communication with an interior of the pipe. The axially elongate duct has through-holes formed through a wall thereof, communicating the interior of the pipe with an exterior thereof. A second, axially extending, tubular pipe, has an axial opening in a sidewall thereof, the axial opening spanning at least a portion of an axial extent of the second pipe. The first pipe is substantially nested within the second pipe and the axially elongate duct projects radially outwardly through the axial opening. A combination gas valve and pressure regulator fluidly connects hydrogen gas with the first pipe. An igniter ignites and initiates combustion of the hydrogen gas exiting from the first pipe and duct via the through-holes.

A combustion membrane (14) for a gas burner (2) comprises a fabric or mesh (21) of interlaced metal wires (22), having two opposite interlacing surfaces (19, 20) forming a combustion surface (19) and an inner surface (20) of the fabric / mesh (21), respectively, wherein the metal wires (22) are formed by continuous metal fibers (22') which form a yarn (22) of mass by length in the range from 0.8 g / m to 1.4 g / m.

A burner includes a mixing chamber having therein a space in which fuel and air are mixed to form a mixture, a chamber lower cover that is coupled to the mixing chamber while covering an opening formed in the mixing chamber in a reference direction and has a combustion opening opened in the reference direction, a porous distribution unit that includes a metallic sintered material, through which the mixture passes in the reference direction, and covers the combustion opening, a distribution plate that has a plurality of distribution through-holes, through which the mixture passing through the porous distribution unit passes, and covers the combustion opening on the downstream side of the porous distribution unit in the reference direction, and an ignition unit that covers the combustion opening on the downstream side of the distribution plate to ignite the mixture passing through the distribution plate.

A burner is provided with: a combustion tube forming a combustion chamber for burning a fuel; at least one nozzle pipe for injecting a gas containing the fuel or air into the combustion chamber, the at least one nozzle pipe being disposed inside the combustion tube; and a nozzle plate extending, inside the combustion tube, along a plane perpendicular to an axial direction of the combustion tube, and having at least one hole into which a tip portion of the at least one nozzle pipe is fitted, respectively. A hole forming portion of the nozzle plate in which the at least one hole is formed includes SiC or graphite, and the tip portion of the nozzle pipe includes an Fe-Cr-Al based alloy.
